Dear Developer,

After updating to the latest beta software (iOS version 26.4), the AI Keyboard is not activating on the keyboard. Please check and address this issue.

Update:

### 1/5 — Leider aktuell unbrauchbar

*2026-06-28*

Theoretisch handelt es sich um die beste Tastatur auf dem Markt. Bedauerlicherweise funktioniert jedoch die deutsche Spracheingabe in den Anwendungen nicht einwandfrei. Es scheint ein Fehler oder ein Bug vorzuliegen. Da ich überwiegend die Spracheingabe nutze, erweist sich die App somit als für mich unbrauchbar.

### 5/5 — Super App

Funktioniert einwandfrei. Nach kürzlichen updateproblemen an den support gewandt und nach einem tag war ein neues Update draußen.... Top 👍🏼

### 4/5 — Crash please notice & update
